Because of laser's harsh electromagnetic environment  LCD module coupled to the electromagnetic interference easily  leading to not work normally. This paper analyzed the interference coupling mechanism. On the basis of the analysis results  LCD module's field-line coupling is calculated by Taylor form's BLT equation. The calculation result is verified by experiment. The results show that  due to the field-line coupling  the data line of LCD module existed interference voltage  interference voltage value is 1V. The interference voltage is larger than the LCD module's noise margin. LCD module must shield the interference. 2012 IEEE.   A small thickness measurement system based on PSD and FPGA (EI CONFERENCE) 会议论文  OAI收割 3rd International Conference on Measuring Technology and Mechatronics Automation, ICMTMA 2011, January 6, 2011 - January 7, 2011, Shanghai, China 作者:  Guo J.;  Guo J.;  He X. 收藏  |  浏览/下载：30/0  |  提交时间：2013/03/25 Considering that the requirement of industrial manufacture  An AT89S51 singlechip works as the core processor of the system. By two laser triangulation  a small thickness measurement system based on PSD and FPGA is presented. It takes S3931 PSD of one dimension as position detection device  A FPGA produces logic control signals for the whole system  the small displacement is converted to differential voltages  which is made by Hamamatsu in Japan  and after amplification and A/D transformation  8-bit parallel data is send to singlechip from FPGA by external interrupts  and the final calculation results output to the LCD display module. After digital micro meter calibration  we get the small thickness. Experiments show that the detection accuracy of the system is not less than 10um.
